11x^2-2x+9=0

解方程11x^2-2x+9=0

解题11x^2-2x+9=0 方程

简化
11x2 + -2x + 9 = 0

重新排序条件:
9 + -2x + 11x2 = 0

解：
9 + -2x + 11x2 = 0

求解变量 'x'.

开始做平放. 将所有条件除以
11 平方项的系数: 

两边除以 '11'.
0.8181818182 + -0.1818181818x + x2 = 0

将不变的条件移到右边:

增加 '-0.8181818182' 到方程的每一侧.
0.8181818182 + -0.1818181818x + -0.8181818182 + x2 = 0 + -0.8181818182

重新排序条件:
0.8181818182 + -0.8181818182 + -0.1818181818x + x2 = 0 + -0.8181818182

结合相似条件: 0.8181818182 + -0.8181818182 = 0.0000000000
0.0000000000 + -0.1818181818x + x2 = 0 + -0.8181818182
-0.1818181818x + x2 = 0 + -0.8181818182

结合相似条件: 0 + -0.8181818182 = -0.8181818182
-0.1818181818x + x2 = -0.8181818182

这个 x 项是 -0.1818181818x. 取其系数的一半 (-0.0909090909).
该平方 (0.008264462808) 并将其添加到两侧.

增加 '0.008264462808' 到方程的每一侧.
-0.1818181818x + 0.008264462808 + x2 = -0.8181818182 + 0.008264462808

重新排序条件:
0.008264462808 + -0.1818181818x + x2 = -0.8181818182 + 0.008264462808

结合相似条件: -0.8181818182 + 0.008264462808 = -0.809917355392
0.008264462808 + -0.1818181818x + x2 = -0.809917355392

一个完整的平方在左侧:
(x + -0.0909090909)(x + -0.0909090909) = -0.809917355392
